ANY aggregation of parts assembled to obtain a mechanical result is a series of compromises. The relative importance of the objectives governs the nature of the compromise. The major objectives to be considered in the design of airplane engines are The automobile engine must have Starting from these basic qualities, the author makes a close comparison of construction, methods of use, adaptations and elimination of parts, weights and fuels. The question of design of crankshafts and crank cases is discussed. The action of an airplane engine in an automobile and the changes needed to insure success are specified. The conclusion is reached that none of the major features of the airplane engine can be grafted directly upon the automobile. The automobile will be improved as a result of airplane experience, but this improvement will be evident in the service the automobile gives, rather than in radical changes of design.
